Used in on my ductless mini-split A/C units
If you have one of the ductless mini-split air conditioners, SOMEONE is going to have to do maintenance on it, or it will become useless. Maybe someday they'll be re-designed to be lower maintenance, but till then, if you don't keep the coils clean, the 'drain pan' (which is quite small & narrow) clean, and the drain line open, you're going to have water intrusion & big trouble. My two Klimaire units didn't have any issue until the second year of svs. I live in the middle of Tx, maybe not the hottest place on earth, but our summer months are plenty hot. I had several A/C techs out when one of the units began leaking water down the inside wall, & they were clueless as to what the problem was.
Long story short, coils & drain pan needed cleaning, which is where this Evap Foam spray on cleaner, comes in. Someone is going to have to partially disassemble your mini-split to clean the drain pan, & clean the coils. After a lot of money spent on ignorant a/c techs, I began doing this task. This Nu-Cal is the only brand I've tried so far, & I don't think there are a lot of equivalents at this point, & I've got a couple of cans ready to go for the next time I need them. Ductless systems 'can' be great, but either you, or someone is going to have to properly maintain them, and if it's not you, you best know a professional that is familiar with how to keep them properly serviced.
